This guide for using bio-slurry for commercial fishponds was developed as part of an experimental study to estimate the effects of using bio-slurry in fish ponds and identify methods for using it. The aim is to carry forth some information to help farmers use bio-slurry from biogas for growth out ponds.
It describes the pond preparation; fingerlings selection; bio-slurry preparation; method of applying the effluent; feed monitoring; pond environment monitoring and fish health.
Bio-slurry from biogas production has many advantages when used in aquaculture (reduced risk of infection in fish; increasing the growth rate of fish because of more effective nutrient enrichment aquatic biota in the pond). The growth rate can increase, and the survival rate of fish as well, while reducing the coefficient of food. As a result, ultimately it increases the economic efficiency of the pond compared to the fresh material used to fertilise ponds.
To safeguard the quality of biodigesters, it is important that effective quality control mechanisms are formulated and properly enforced. The quality of construction, operation and maintenance of biodigesters has to be a major concern and supervisors have to play vital role in this regard.
In the process to build the capacity of local artisans especially the masons and supervisors, by imparting them detail technical knowledge and skills on methods of construction and supervisions of the household Biogas Plant, a Training of Trainers (TOT) has been felt needed. The overall objective of the TOT is to build capacity, especially within provincial Agriculture and Rural Development Offices, to conduct quality training courses on the Construction and Supervision of Biodigesters. The participants of TOT are expected to organise and conduct technical training programs to masons and supervisors in the future.
The document contains the following chapters:
